Worked on the hasaneyldrm/exercises-dataset repository to deliver Russian language support and establish a foundation for internationalization. Focused on implementing translation strings and updating the HTML-based user interface to support locale-aware experiences, enabling the application to accommodate multilingual content and future locale expansion. The technical approach involved integrating internationalization (i18n) workflows and ensuring UI elements could dynamically switch languages, improving accessibility for a broader user base. No major bug fixes were recorded during this period, with efforts concentrated on feature development. The work laid a scalable groundwork for adding additional locales and demonstrated proficiency in HTML and i18n practices.
